cd5d03811d mpegtsmux: Wait for data on all pads before deciding on a best pad unless timing out
This makes sure that if upstream has different latencies that we're still
outputting buffers with increasining timestamps across the different streams
unless buffers are arriving after the latency deadline.

f8246327ef mpegtsmux: Allow pads to have no caps until they receive their first buffer
If the muxer times out because of the latency deadline it can happen
that some pads have no caps yet. In that case skip creation of streams
for these pads and create updated section tables once the first buffer
arrives later.

4f33bc8932 mpegtsmux: Correctly time out and mux anyway in live pipelines
This makes sure that for sparse streams (KLV, DVB subtitles, ...) the
muxer does not wait until the next buffer is available for them but
times out on the latency deadline and outputs data.

For non-live pipelines it will still be necessary for upstream to
correctly produce gap events for sparse streams.

b405ff34d3 mpegtsmux: allow attaching PCR to non-PES streams
There is an existing PMT mapping between PCR_%s and an mpegtsmux sink
pad name, where %s equals the program number that the PCR corresponds
to. We re-purpose this functionality to also support a mapping between
PCR_%s and an arbitrary PID. If this mapping is set, then the header PCR
PID is set to this value, and PCR is attached to the stream with this
PID.

Note: the current implementation also attaches PCR to the video stream,
so this may be inefficient.

a72ca72a27 mpegtsmux: add stream-number property on GstBaseTsMuxPad
This new property allows setting of PES stream number for AAC audio
and AVC video streams.

The stream number is subject to the following constraints:

1. it must be between 0 and 15 for video
2. it must be between 0 and 31 for audio

Currently the PES stream number is hard-coded to zero for these
stream types.

52c419b799 mpegtsmux: Disable aggregator's default negotiation
mpegtsmux can't negotiate caps with upstream/downstream and always outputs
specific caps based on the input streams. This will always happen before
it produces the first buffers.

By having the default aggregator negotiation enabled the same caps
would be pushed twice in the beginning, and again every time a
reconfigure event is received.

95ff949eff mpegtsmux: Start last_ts with GST_CLOCK_TIME_NONE
And use the output segment position for the outgoing timestamp while it
is. This is needed to delay the calculation of `output_ts_offset` until
we actually have a usable timestamp, as tsmux will output a few initial
packets while `last_ts` is still unset.

Without this, the calculation would use the initial `0` value, which did
not have the intended effect of making VBR mode behave like CBR mode,
but always calculated an offset equal to the selected start time.

c2eeb639b0 basetsmux: fix SCTE pts_adjustment with offsets
When there are elements between the demuxer and the muxer that
introduce an offset to the running time, or when offsets are
set on pads by the application, this shift must be taken into
account when calculating the final pts_adjustement.

c3a161f287 basetsmux: rework SCTE section handling to handle passthrough
mpegtsmux can receive SCTE sections from two origins: events
created by the application, and events forwarded downstream by
mpegtsdemux, containing sections that may not have been fully
parsed, and additional data to help tsmux translate times to
the correct domain, both for requesting keyframes and calculating
an accurate pts_adjustment.

The complete approach is documented further in a comment above
the relevant function.

be4d0fff23 basetsmux: extend SCTE 35 support
Makes it possible to support passing SCTE 35 cue points from
demuxer to muxer, while preserving correct timing.

This will also improve ex nihilo cue points injection, as splice
times and durations are now interpreted as running time values,
and may trigger key unit requests.
